BITE-HANDLING- MEANS.

Specification of Letters Patent.

Patented June 24, 1919.

Application filed August 13, 1918. Serial No. 249,679.

To all whom it may concern:

Be it known that I, WILLIAM WV. MAN- NING, a citizen of the United States, residing at Mountainair, in the county of Torrance and State of New Mexico, have invented a new and useful Pipe-Handling Means, of which the following is a specification. 7

It is one object of this invention to provide a simple means whereby a string of piping, in a well, may be gripped securely at any time, to prevent the piping from sliding downwardly.

In the accompanying drawings Figure 1 is a side elevation; Fig. 2 is a section on the line 2-2 of Fig. 1.

In carrying out the invention there are provided jaws 1 and 2, supplied at their lower ends with feet 3, which may be loopshaped. The feet 3 are downwardly convexed as indicated at 4:, so as to cooperate properly with the support on which they are mounted, the feet being attached to the jaws 1 and 2by means of securing elements 5. The inner edges of the jaws 1 and 2 are curved longitudinally as shown at 6 to form cams, adapted to grip the pipe. The cam edges 6 of the jaws 1 and 2 are supplied with teeth 7 and are concaved transversely, so as to receive and support the pipe properly. On the upper edges of the jaws 1 and 2, handles 9 are mounted. The numeral 10 marks a pair of connections, preferably in the form of strips. At one end, the strips or connections 10 are united by a pivot element 11 with the jaw 1. The connections 10 are provided with openings 12 in which a securing device 14: may be inserted, the securing device being mounted in the jaw 52.

In practical operation, the pipe between the jaws 1 and 2 is gripped firmly by the jaws, and cannotslide downwardly. Since the securing device 14 is adjustable in the openings 12 of the connections 10, the jaws 1 and 2 may be separated to any desired ex tent, to receive pipes of different sizes. Since the feet 3 are concaved as shown at 1, the feet will rock on a support, and permit the jaws 1 and 2 to grip the pipe.

Having thus described the invention, what is claimed is 1. In a device of the class described, a pair of opposed jaws having their inner edges curved to form cams; downwardly convexed feet at the lower ends of the jaws, the feet being exposed to bear upon a sup port and to form rockers for the jaws; and an adjustable connection uniting the jaws above the feet, whereby the distance between the jaws may be adjusted.

2. In a device of the class described, a pair of opposed jaws having their inner edges curved to form cams; downwardly convexed feet at the lower ends of the jaws, the feet being exposed to bear upon a sup port and to form rockers for the jaws; and means for pivotally connecting the jaws above the feet.

In testimony that I claim the foregoing as my own, I have hereto affixed my signature in the presence of two witnesses.

WILLIAM W. MANNING.
